ABSTRACT
Until 2000, the city population data published in the United Nations Demographic Yearbook were not computerized in any publicly accessible form. Thanks to the efforts of Alice Clague of the United Nations, the panel was able to secure a new database (United Nations, 2000) containing a prepublication version of the city population data that appear in the 1998 Demographic Yearbook. Although our computer file lacked some of the detail of the published table, it supplied the framework we needed to construct the merged city population dataset used throughout this report. To lengthen the time span of these data, we supplemented the computer file by keying in city population data from three earlier years of the Demographic Yearbook (United Nations, 1987, 1992, 1998a).
